Hub. N. Queensland, Kuranda (Turner), May 1913; 

 Mackay (Turner), September 1899. 



Ipobracon gilberti, sp. n. 



$. Variegata; capite flavo; prothorace mesonotoque rufisj anten- 

 nis, mesopleuris, mesosterno, scutello, segmento mediano, seg- 

 ments abdominalibus tertio apice, quarto sequentibusque, valvulis 

 terebrae, pedibusque intermediis posticisque nigris ; segmentis 

 abdominalibus primo, secundo, tertioque basi ochraceis ; segmentis 

 4-7 dorsalibus apice angustissime albido - marginatis ; femoribus 

 intermediis apice, tibiisque intermediis basi fusco-femigineis ; alis 

 fusco-hyalinis, stigmate venisque fusco-testaceis. 



Long. 11 mm.; terebrae long. 8 mm. 



$. Closely allied to /. quaclricolor ; but is a larger species, with 

 the face distinctly punctured; the basal area of the second tergite 

 is large, forming an equilateral triangle, the grooves bounding it 

 indistinct, the raised areas at the basal angles large, touching the 

 median area at the base, the lateral grooves not reaching the apex 

 of the segment ; the apical margin of the segment shallowly emargin- 

 ate in the middle. Third tergite without a raised median area, 

 the areas at the basal angles fairly large. Second suture smooth. 

 Otherwise as in quadricolor, but the recurrent nervure almost 

 interstitial. 



Hob. N. Queensland, Mackay (Turner), October 1899; 

 Kuranda (Turner), November, May and July. 



This species, together with pallidicolor and quadricolor. 

 seems to be related to the New Guinea species I. elegans, 

 Szep. In all these the second tergite is much broader than 

 long, as is usual in Australian species of the genus. 



Ipobracon torridus, sp. n. 



$. Rufa ; capite pedibusque ant iris intermediisque rufo-flave- 

 scentibus; abdomine ochraceo ; antennis, pedibus posticis, valvu- 

 lisque terebrae nigris; alis subhyalinis, leviter infumatis, venis 

 fusco-testaceis. 



Long. 11 mm.; terebrae long. S mm. 



$. Though very differenl in colouring I cannot find thai this 

 differs either in sculpture or structure from /. gilberti. I do not 

 think, however, that it can be a mere colour variety of that species.
